is there a way to alter the spacing of any Delphi FMX component ? all are doubled spaced between lines i believe, i'm sure there is a way to edit the spacing between lines. the most important that it work for FMX
The difference between the two screenshots isn't that they have different line heights or line spacings.
The difference is that the left application is using a variable-width font, while the right application is using a fixed-width (monospaced) font.
You can see this extremely clearly in the top centre part of the image, where you have four full stops (....).
I assume you consider the right screenshot to display the desired appearance. If so, the solution is to change the font in the left application to a fixed-width (monospaced) font.

I would like to align the start of the text of two UILabels. I aligned the two UILabels (with the yellow and grey background) and used sizeToFit: to shrink the UILabels to the content but the text is not perfectly left aligned. There is a gap on the left. The gap is bigger or smaller depending on the first character. I would like to align the red lines in the following picture. There is even a small gap with the small font in the grey UILabel but it's barely visible.
With the Z character the gap is smaller but still visible by the yellow area left to the Z
A simple UILabel alignment does not help for my specific problem, because the text content is dynamic and not static. So there could be any combination depending on the data I get from the backend. Therefore I was hoping for a UIFont or UILabel attribute that could return the size of the gap based on the current rendering of the text.
I know that there are great UIFont related attributes like baseline, capHeight and ascender one can access to align text but there seems to be no attribute that would return the value of this gap on the left.
If this doesn’t need to be two UILabels, you could have one with attributed text. Then both lines would be subject to the same layout.
I haven't tried the GUI which people have been posting Screen Shots of, however... the behaviour is consistent with the very nature of typography.
The font sizes are completely different, therefore the width of an em is different, subsequently the letter-spacing is also different.
See this: http://www.w3.org/WAI/GL/css2em.htm for more information.
I know this answer doesn't give you what you have asked for, however it should explain why this is happening.
For customisation such as this (if HTML and CSS) I would use a negative / positive margin on the sub text, however seeing as you are using backgrounds use padding (or the equivalent in your GUI).
Use attributed text of UILabel
set indentation as per your requirement

Select both the labels and add a constraint called align leading edges.
I am using a custom .ttf font called Classic Robot in my iOS app. I am trying to add Japanese translation and this font appears to not support Japanese characters. This is not a problem initially because it appears iOS automatically changes the font to the system default font which can support Japanese.
My issue is that these two fonts have different vertical alignment when rendered by iOS as in the below pictures. As you can see, the Japanese font is aligned near the top of the white box (which is the frame) whereas the English font sits somewhere near the middle. This makes it difficult for me to layout text properly. Does anyone know why this might be the case?
I believe it might have to do with the ascender and descender properties on the iOS font I cannot be certain.
Your question is: "Does anyone know why this might be the case?"
The answer is that the ascender property of the Japanese font is smaller than the Classic Robot one. This can be fixed by generating a custom Japanese font that has an ascender property large enough to make it match the spacing you get from the other font. This can be done by downloading the Apple Font Tool Suite and following the instructions posted in this answer.
Also for buttons you can solve the issue by increasing the insets:
myButton.contentEdgeInsets = UIEdgeInsetsMake(15.0, 0.0, 0.0, 0.0);
You can specify a different value for each of the four insets (top, left, bottom, right). A positive value shrinks, or insets, that edge—moving it closer to the center of the button. A negative value expands, or outsets, that edge. This works for the button image and button title.
Moving from TBX to SpTBX. I used in the past TTbxDockablePanel which has such props:
DockedWidth
DockedHeight
FloatingWidth
FloatingHeight
I can't find such properties in SpTBX panels, so how should I change my code to use such props? ie. i need to get/set SpTBX panel's docked width/height and floating width/height.
DockedWidth and DockedHeight
A TSpTBXDockablePanel now has a property DefaultDockedSize. A docked panel is docked to either a vertical or horizontal dock, so it only needs one size, which specifies the width (in a vertical dock) or height (in a horizontal dock.) The length of the other axis is a result of either the dock size or the other panels in the same dock. If there are other panels, the size it becomes is the width of the other panels in the dock. If there aren't, it will use either the previous size (if DefaultDockedSize is 0) or try to use DefaultDockedSize.
See TSpTBXCustomDockablePanel.SetParent for the code. You'll be interested in the two branches beginning if ToDock then... and if ToFloating then.... There are some comments there that I've tried to interpret to write the above.
From memory, when I converted from TBX to SpTBX years ago, this was the hardest area to get behaving exactly the same. However, you can get it to behave 'okay', ie with behaviour that makes sense, easily.
FloatingWidth and FloatingHeight
Replaced by FloatingClientWidth and FloatingClientHeight. Note that these are the client sizes not window sizes, but in general they should be direct replacements.
In addition
There is a comment at the top of the SpTBXDkPanels.pas file,
// - To handle the size constraints use GetMinMaxSize when the DP is floating,
// and ConstrainedResize when is Docked (explicitly check if it's docked).
You might find that useful too.
There are a reasonable number of comments scattered through the code. The SpTBX library doesn't have very good documentation, but it does come with high-quality source... Use the source, Luke :)
I have been adding icons to my mobile control Line Item controls and haven't quite figured out what the preferred size of these icons should be. The CSS has max size settings of 35 by 35px.
The reason I ask this is because the icons don't seem to line up correctly. The CSS positions them at 0 0. If all else fails I may modify CSS and position them to something other than 0 0.
Still interested in hearing how you have dealt with this.
In the teamroom template, the mobile view for Recent Activity has icons that line up with the text. All these images are 16 X 16px.
There will never be 1 fit for all, the layout will be dependant on font size, row height and where you want it to line up. Some people may want it to align in the middle vertically and others will want it to align with the title in the row.
I would say 21px x 21px. but that depends on what font-size you are using.
Icon size can depends upon the applicaton. Normal size is 32x32 and an extended icon size is 64x64. If you want to line up the icons, you might have to change the icons to a standard size.
In Delphi 7 IDE, do the lines need to be a given length? I see a gray line in some Delphi code I'm working with, and it looks like ever line ends right before it.
It's called the right margin. It is intended as a guide to help you avoid writing lines that are too long and exceed your coding standards. You can switch it off from the Editor Options, as I have done here:
It's just a guide to line length. Some people don't like long lines because they can be hard to read on different resolutions or when doing comparisons.
That gray line is called the margin.
You can set its visibility and position in the Editor Properties at the Display tab in the Margin and gutter groupbox.
The margin is a visual assistent. The standard position is 80 characters, which defaults to the maximum unscrolled size of many source formatting output media, such as the one used here at Stack Overflow. Originally, it had something to do with the paper width on (matrix) printers. Maybe it still does.
